Hey folks,

I'm having some trouble with my keyboard/mouse combo.

Windows XP SP3, newest Setpoint, and logitech mx 5500 set.

My keyboard keeps dropping its connection for a few seconds and then has to reconnect (does it on its own) before I can continue typing.

I uninstalled/reinstalled everything and then noticed that in my device manager, I don't get the hardware listed properly.

The unknown devices are my MX5500 USB adapter (bluetooth dongle). When I uninstall them, and then unplug/replug the adapter, I get the WinXP installation business, and then it fails without finding appropriate drivers. Then these icons show up in the device manager.

I tried the Broadcom Bluetooth updater - it won't recognize any bluetooth devices connected to my system, even with the adapter plugged into any of the USB ports.

It seems my XP is missing its bluetooth drivers?!

Any ideas?
